I have no idea why they're even remotely interested in Windows as a product anymore. Surely they can't expect that much revenue from integrated AI services when most of the general public's needs can be covered by web services that will severely outmatch Microsoft's development speed (y'know because of juggling legacy code and all).
Considering the fact that they gain most of their revenue by far from their Azure cloud services and enterprise customers, it just seems like a stupid business decision to invest this much into all kinds of random features for their desktop OS aimed at consumers.
In proper systems architectecture theory, we generally try to avoid mixing up functionality this much because a modular design allows your system to evolve without too much pain. Why build all this crap into Windows when you can just opt-in by installing an application for it?
